Summary

Researchers evaluated neopentyl glycol as a solvent for glycolysis of complex PET waste streams and developed an effective purification process, achieving over 90% purity in the recovered monomeric products. These results suggest neopentyl glycol is a viable alternative for chemical recycling of difficult PET waste into high-quality, value-added materials.

Neopentyl glycol (NPG) was evaluated for glycolysis of complex PET waste streams, and an effective purification process was developed. Monomeric products achieved over 90% purity, making them suitable for high-quality, value-added applications.
